GM annouces the G6 convertible today. Couple of interesting tidbits...
The G6 hardtop convertible is built on the same platform as the coupe, but was strengthened in key areas to bolster vehicle rigidity. As a result, the G6 hardtop convertible has the same solid ride and precise panel fit as the G6 coupe.
A unique two-piece clamshell-style retractable hardtop was engineered with input from renowned German coachbuilder Karmann. It is the world’s largest retractable hardtop. A long top was necessary to enclose the spacious interior. The top’s backlight is glass with a standard defogger.
A double-hinged trunk lid facilitates stowing the top. It opens like a conventional trunk for cargo storage, but is reverse-hinged to accept the folding hardtop. A hard tonneau cover automatically appears as part of the hardtop retraction process, and there is no visible “stack” when the top is down – it simply disappears into the storage compartment. It operates with the touch of a single button, and the entire process takes less than 30 seconds. When the top is stowed, the trunk still provides 1.8 cubic feet (61 liters) of cargo space. With the top up, trunk capacity increases to 5.8 cubic feet (164 liters).
The door glass for the coupe and convertible automatically indexes (up and down) about 0.25-inch (6 mm) when the doors of the vehicle are opened and closed. This precision feature is more commonly found on upscale European cars, and is an example of the G6’s attention to detail. Additionally, a specially insulated headliner further quiets the raised top. It provides both acoustic and thermal protection. G6 convertibles are subjected to a stringent water test at the assembly plant.
